CROSS REFERENCE TO RELATED APPLICATION

The current application claims priority to and the benefit of U.S.Provisional Patent Application Ser. No. 61/563,421 filed on Nov. 23,2011, entitled “MUZZLE BRAKE COVER WITH BLAST DIVERTER”. This referenceis hereby incorporated in its entirety.

FIELD

The present embodiments generally relate to a muzzle brake coverproviding blast diversion for firearms.

BACKGROUND

Muzzle brakes are designed to reduce the recoil that occurs when a rifleis fired. The recoil of a rifle occurs because of at least two forcesthat are related to the firing of the projectile.

The first force is the force that the explosive powder expends on boththe projectile and the rifle, which is applied in all directions equallyand propels the projectile.

The second force comes from the burst of combustion gases that followthe departure of the projectile from the chamber of the rifle.

Muzzle brakes work by diverting the expanding gases at an angle, whichprevents the force from being translated toward the person firing theweapon.

However, the reduction in recoil achieved by a muzzle brake has the costof increasing the sound perceived by the user as well as increased leadexposure for the user and nearby bystanders.

A need exists for a muzzle brake cover which can divert the soundsproduced by the muzzle brake.

A further need exists for a muzzle brake cover that can reduce orprevent the flow of toxic particles from the barrel of the rifle,through the muzzle brake, to the user.

The present embodiments meet these needs.

DETAILED DESCRIPTION OF THE EMBODIMENTS

Before explaining the present apparatus in detail, it is to beunderstood that the apparatus is not limited to the particularembodiments and that it can be practiced or carried out in various ways.

The present embodiments generally relate to a muzzle brake coverproviding blast diversion for firearms.

The muzzle brake cover can provide benefits of both having a silencer orusing only a muzzle brake, by interchanging the silencer and the muzzlebrake cover in the field.

The muzzle brake cover can divert blast and damaging sound away from theshooter, which can protect the shooter and nearby individuals from lossof hearing.

The muzzle brake cover can protect the muzzle brake from externaldamage, such as damage to the threads or attachment surfaces forsuppressors.

The muzzle brake cover can provide blast diversion by extending beyondthe muzzle brake.

The muzzle brake cover can increase the marketability of currentlyexisting muzzle brakes, which can stimulate economic growth in thefirearms sector.

The muzzle brake cover can have an extension adapted for attachment onan end of a muzzle brake or flash suppressor of a gun.

The extension can have a cylindrical inner surface with a diameterlarger than that of the outer diameter of the muzzle brake or flashsuppressor. For example, a muzzle brake cover with an extension that hasa diameter of 23 millimeters designed to fit over a 19 millimeters outerdiameter muzzle brake.

The extension can have concentric rings. The concentric rings can extendaround the inner walls of the extension. The concentric rings can assistin flash suppression or blast diversion, such as concentric rings withinternal cuts are designed to offer resistance to expanding gas movementand reducing lateral or rearward noise away from the user.

The muzzle brake cover can have a threaded portion which can extendaround the inner walls of the extension. The threaded portion can engagea muzzle brake, such as one or more threads designed to connect with theouter surface of the muzzle brake.

The muzzle brake cover can have a smooth portion disposed between theconcentric rings and the threaded portion, such as a smooth portionmaking up about 5 millimeters of the inner surface of a muzzle brakecover between the concentric rings and the connecting means.

The extension can have the threaded portion for fitting over portions ofthe muzzle brake, such as threads or an external clamping mechanismwhich allow the muzzle brake cover to be affixed to either the barrel ofthe rifle or to the muzzle brake itself.

The muzzle brake cover can have a collar comprising a plurality oftightening surfaces. The tightening surfaces can allow quick tighteningof the muzzle brake cover over a muzzle brake or flash suppressor of afirearm, such as a hand-tightenable threading with a grippable surfaceto allow quick connection to the muzzle brake.

The muzzle brake cover can have a threaded portion which can have aconnecting means for engaging a muzzle brake or a flash suppressor, suchas threads, a clamp, a hex head, or an external clamping mechanism.

The muzzle brake cover can have a muzzle brake, which is a device thathas a bore through which a projectile and propelling gas pass in exitingthe muzzle of a firearm.

An embodiment of the muzzle brake cover can connect with a muzzle brakewhich has a bore with at least one opening for venting a portion of thepropelling gases which can create a directional reaction force foroffsetting a recoil or other motion of the muzzle when the firearm isfired, such as a muzzle brake designed to vent expanding gases laterallyto dissipate the force of ejecting the projectile.

The muzzle brake cover can have a flash suppressor which has a chamberwhich can include a slot, a groove, a baffle, or combinations thereof.The flash suppressor can have a bore in line with the path of theprojectile and can have a gas exit channel or slot for exhausting ordiverting a portion of the propellant gases with the respect to the pathof the projectile, which can reduce a flash signature emanating from thefirearm.

The muzzle brake cover can have concentric rings which can be equallyspaced apart with a cut depth which does not penetrate the wall, such asconcentric rings which can be formed 3.2 millimeters apart with a cutdepth of 1.5 millimeters.

Though the cut depth here is depicted as being equal, the cut depth canvary between either consecutive or non-consecutive concentric rings.

The concentric rings can extend up to the entire length of the muzzlebrake, such as concentric rings which cover from about 20 percent toabout 80 percent from one end of the muzzle brake cover to the smoothportion.

The muzzle brake cover can have one or more concentric rings which canhave a square cut.

The muzzle brake cover can have one or more concentric rings which canhave a bevel, such as a bevel of about 30 degrees inclined towards thebore in line with the front end.

The muzzle brake cover can have a smooth portion which can provide aclearance between the slots on the muzzle brake and the smooth portion,such as a clearance from about 0.5 millimeters to about 3 millimeters.
